SpaceX rocket set to crash into the Moon after seven years in space

A leftover SpaceX Falcon 9 rocket stage is on course to collide with the Moon on March 4, 2022, after seven years adrift in deep space. The spent booster, launched in 2015 to deploy a climate satellite, has been tumbling along an unpredictable orbit ever since. Astronomers expect the high-speed impact to kick up a visible plume of lunar regolith, offering a rare chance to study the Moon’s surface composition.

A seven-year detour ends in a lunar strike

The rocket stage, part of SpaceX’s Transiting Exoplanet Survey Satellite (TESS) mission, was never intended to return to Earth or the Moon. Instead, it was left in a chaotic trajectory influenced by the gravitational pull of the Earth, Moon, and Sun. Over time, its orbit decayed until it set a direct course for the lunar surface. Bill Gray, an independent astronomer tracking the object, confirmed the collision date after refining orbital calculations with input from other observers.

What astronomers hope to learn

The impact site, near the Hertzsprung Crater on the Moon’s far side, will be monitored by telescopes on Earth and in orbit. The crash is expected to excavate material from beneath the surface, creating a bright flash and a debris cloud that could reveal clues about the Moon’s composition. While the event itself poses no risk to Earth, it highlights the growing challenge of tracking and managing space debris beyond our planet’s immediate orbit.

Why it matters

This unintended lunar impact underscores the long-term unpredictability of space debris, even for missions designed to avoid Earth re-entry. As private spaceflight and lunar exploration ramp up, the incident serves as a reminder of the need for better tracking systems and international protocols for end-of-life disposal of spacecraft. For astronomers, it’s an unexpected opportunity to gather data that could inform future lunar missions.
